I would check mailbox 799 and use advanced to see if it has an alternate extension of what you might consider the main number
Thanks, it does have 3 alternate extensions. 830, 840 and 899. 830 and 840 are ring groups. 899 is the alternate to the main numbers.
This I assume means when alternate night1/2 is triggered and passes into NuPoint (770), it looks at what extension sent it there and triggers the mailbox message for that mailbox.
